We want to use MMZ09332BT1 in the 400 MHz band.
We made a PCB of our transmitter with an output amplifier MMZ09332BT1 with following the example of datasheet for the band of 400-500 MHz. But the output of the amplifier breaks after a short worktime . Vcc1=Vcc2+4,5V. Vbias=3,7V.
We use FR4 instead Rogers RO4350B.
What is the cause of failure?
Could you send a working evaluation board for the band of 400-500 MHz?
Are pins 4, 5 ground or not?
